Erin can be seen entering the BP about 3.19pm and walking towards the toilet.
She exits the toilet about 9 seconds after entering.
She can then be seen looking at the sandwiches in the fridge section, before walking over to another area of the service station, which is out of view.
She makes her purchase before leaving about 3.22pm.
In the footage, Erin is wearing a grey sweater, cream pants, black sandals and a black crossover bag.
She wore CREAM PANTS? ----Not the pants I'd choose if I felt 'unwell' from food poisoning.
